Abstract

Un procédé permettant d'optimiser une forme d'onde d'un courant électrique appliqué à une électrode comprend les étapes suivantes: l'application d'un courant électrique à une électrode d'un dispositif; la détermination d'une forme d'onde de la tension ou de l'intensité du courant électrique; la représentation de la forme d'onde par une description mathématique telle qu'un nombre de points ou une fonction analytique caractérisée par un nombre de coefficients inconnus et un nombre fixe de fonctions connues; la mesure d'une fonction du dispositif associée à l'application du courant électrique; l'introduction d'une description de la forme d'onde et des mesures dans un algorithme, qui peut être un programme informatique ou un autre dispositif de calcul comprenant des calculs manuels, dans lequel une routine d'optimisation utilise les points ou les coefficients en tant que variables indépendantes pour optimiser le fonctionnement du dispositif; et l'exécution des calculs pour déterminer des valeurs des points ou des coefficients qui optimisent le fonctionnement du dispositif et déterminent ainsi une forme d'onde optimisée du courant électrique devant être appliqué à l'électrode du dispositif.
